hi,
if you are a C# programmer, you should be able to create your own function that will check the type. you could use the try-catch block to convert it to the desired type. if it completes with a success, you know it is of the right type.

The int.TryParse and float.TryParse static methods are useful for this.

One technique you can use is to include the Microsoft.VisualBasic dll and use the 'IsNumeric()' method.
Just add a reference to the Microsoft.VisualBasic (assuming .NET 2.0 and assuming you've installed VB.NET) and then you can do this:
Microsoft.VisualBasic.Information.IsNumeric("123");
Microsoft.VisualBasic.Information.IsDate("3/21/2007");
There are other available methods so you can review to see if any fit your needs...

hi,
try the following:
dim i as integer = iif(textbox1.Text="",0,textbox1.Text)
please note that it will not check if it is of type integer or not, for that you can use validators.

Hi
It is not the problem with session(your subject).
The problem is how you are redirecting to login page(I think So..).
Can you post it.
To succeed, we must first believe that we can.

Try the following code to redirect
<br />
Response.Write("<script language='javascript'>")<br />
Response.Write("window.open('login.aspx','_top')")
Response.Write("</script>")<br />
To succeed, we must first believe that we can.

I keep getting this error when trying to read items from my shopping cart session. I've tracked it down to the foreach loop I am doing.
Unable to cast object of type 'BasketItem' to type 'BasketItem'.
Exception Details: System.InvalidCastException: Unable to cast object of type 'BasketItem' to type 'BasketItem'.
foreach (BasketItem theItem in items)<br />
{<br />
count++;<br />
total += theItem.ReturnTotal();<br />
}
items is defined as this:
ArrayList items = (ArrayList)Session["shoppingCart"];
Session["shoppingCart"] is defined as the ArrayList cartArray:
ArrayList cartArray;<br />
Session["shoppingCart"] = cartArray;
The BasketItem class is a protected class with a string, an int, and 2 doubles that holds information about the product and price.
I checked the session to make sure the data is in it correctly. It seems to be fine because I can get the data out of the session and bind it to a datagrid with no issues. For some reason it doesn't like me doing a foreach loop.
This works fine:
ArrayList items = (ArrayList)Session["shoppingCart"];<br />
GridView2.DataSource = items;<br />
GridView2.DataBind();
I am lost on this one and hope someone can provide some insight. Thank you.

Represents the error that occurs when an explicit conversion (casting operation) fails because the source type cannot be converted to the destination type.
InvalidCastException Class[^]

I understand the error, but I just can't figure out why it can't convert. It seems like it should.

what does cartArray points to?
try this:
foreach (Object theItem in items)
{
count++;
total += ((BasketItem)theItem).ReturnTotal();
}

Thanks everyone. I figured it out. I believe what I was doing wrong was declaring the BasketItem class in Default.aspx.cs and Default2.aspx.cs (where I was reading the session passed from Default.aspx). I moved the class into the AppCode folder into its own .cs file, commented out the class definition from the other two cs files, and the problem went away.

Still why your name "InvalidTypecast" is unaltered?
